Kordell Stewart, a former NFL player, has filed for divorce from Porsha Williams, his wife and co-star of the Bravo reality show "The Real Housewives of Atlanta."

Stewart, 40, submitted the papers to an Atlanta court on Friday, March 22, records show. He and Williams have not commented about the divorce.

On Tuesday, March 26, Stewart was asked by a fan on Twitter why he stars on "The Real Housewives of Atlanta." He replied: "... supporting the wife. Remember it's just TV. Look crazy, but it's just TV. Appreciate the support though."

On Friday, Williams reTweeted a fan's comment that read: "@MalikaCole: I love @PorshaDStewart relationship with @KSlash10, best couple on rhoa" and replied: "Thanks #traditionallove #teamstewarts."

Stewart, who earned the nickname "Slash" when he played for the Pittsburgh Steelers, says in his filing that their marriage was "irretrievably broken" and that they are currently separated, according to the Associated Press, which added that the two wed on May 21, 2011 and have no children together. Stewart has a son from a previous relationship.

News of the divorce comes following the couple's attempts to get pregnant, as documented on an episode of "The Real Housewives of Atlanta" that aired earlier this month.

"It was disappointing for the test to be negative that day," Williams, who also once suffered a miscarriage while married to Stewart, told Hollywood Life in a recent video interview.

The divorce news also comes amid rumors she may be leaving the reality show after making her debut on the premiere of the current fifth season. When asked about it on Twitter, she replied on Monday, March 25: "Thank you nothing has been decided."

In his filing, Stewart asked the court to rule that neither he nor Williams be ordered to pay alimony and says there are no marital assets to divide. Williams, Stewart says in his filing, is "an able-bodied person, earning income, and is capable of supporting herself."

Cast members of Bravo's numerous "Real Housewives" shows are reportedly paid tens of thousands of dollars per season. Brandi Glanville of "The Real Housewives of Beverly Hills" said on Howard Stern's Sirius XM radio show in February that she was paid $18,000 for her first season on the show and that the more veteran co-stars earned $250,000. Bravo has not released official salary information.
